Super Cell Rubber Fender for Ports and Marine Terminals

Super Cell Rubber Fender for Ports and Marine Terminals

Product Overview

Super Cell Rubber Fender for Ports and Marine Terminals is a fixed axial-compression fender with a hollow cylindrical rubber body and integral mounting flanges. The supplied series covers nominal heights from 400 to 3,000 mm, with catalogue-rated performance at 52.5% axial deflection. The geometry provides a broad mounting footprint for load transfer into the berth structure and is well suited to systems using a steel frontal panel.

A complete cell fender system can combine one or more rubber units with a fabricated closed-box steel front panel, bolted UHMW-PE facing pads, anchors and hot-dip galvanized support/restraint chains. Final fender grade, panel area and chain arrangement are selected from berthing energy, allowable reaction force, vessel hull-pressure limits, installation clearance and project-specific operating conditions.

Structure & Fender System Configuration

Cell rubber element | fabricated closed-box steel front panel | mechanically bolted UHMW-PE facing pads | anchor/embedded parts | weight, tension and/or shear chains as required by the system design.

The front panel is specified in Q355B steel to GB/T 1591-2018 or an approved equivalent unless a different project steel grade is required. The closed-box construction is subject to a tightness/leakage check to reduce the risk of water ingress. External steel surfaces are prepared to Sa 2½ and protected by a project-defined marine coating system aligned with ISO 12944; hot-dip galvanizing is used for chain assemblies where specified. Facing pads are virgin black UV-stabilized UHMW-PE, typically 50–80 mm thick, with final thickness determined by contact pressure, wear allowance and service conditions.

Selection & Inquiry Guide

Step 1 – Define the berthing requirement: Provide vessel type and size range, berth arrangement, design berthing energy, allowable fender reaction and hull-pressure limit.

Step 2 – Select height and performance group: Match the required energy/reaction envelope at the specified operating condition; do not select by nominal fender height alone.

Step 3 – Define the frontal system: Confirm panel dimensions, UHMW-PE facing area/thickness, available installation clearance, anchor interface and required weight/tension/shear chains.

Step 4 – Confirm project conditions and verification: State temperature range, berthing angle/velocity assumptions, applicable design/test basis, documentation requirements and any third-party witnessing.

Key Engineering Advantages

• The 52.5% catalogue-rated axial compression provides a practical energy/reaction selection range for fixed berth fender systems.
• The circular mounting footprint distributes fender loads over a broad support area and integrates efficiently with large frontal panels.
• The cell geometry is stable under normal shear components; system chains can be added where panel weight, tensile load or shear restraint requires them.
• The H400–H3000 dimensional series supports a wide range of berth layouts without creating separate thin pages for individual sizes.
